Are you putting them into the Freescale reserved block where they keep
their factory tuned parameters? I thought that block was preserved
across an erase command.  We'd need enough of the ROM disassembled to
make sure were aren't stomping on Freescale data but I think they
hardly use any of the block.

My original dev boards didn't have addresses in them. Which program
are you using to write them?
